泉州沿海全新世钙质碎屑岩特征及其成因的初步认识
|
摘要
近年在泉州沿海近代海滩上发现的钙质碎屑岩,经研究初步确定其时代为全新世早期,成岩阶段处于高能的水动力环境和温暖的气候条件,成岩作用可能与风暴潮流或地震、海底火山活动引发的海啸等突发性海洋事件有关,对于分析该区气候演变,判别海岸带迁移和海岸升降,进行灾害预测和灾害防治均具一定意义。
In recent years,the calcareous clastic rocks have been discovered in the neoteric beach(along) the coastal area of Quanzhou City and the determined results show that its formation time is the early stage of Holocene Epoch.It is inferred that the rock-forming stage exists in the energetic hydrodynamic environment and mild climate and the diagenesis is relative to the bursting ocean events such as storm-surge currents or tsunamis initiated by earthquakes or submarine volcanic activities.It is of significance for studying the climate evolution of the surveyed area,confirming coastal zone emigration and seashore elevation and subsidence as well as carrying through the calamity foreknowledge and control.
